Exercise 9 – Writing values from a list into a file Complete the function design for the write_most_frequent() function, which takes 4 parameters, a string, a list of tuples, an integer, and another string: • The first string represents the name of the file to write to (with the append usage mode) • The list of tuples contains the information to write. Assume the list has already been sorted. • The integer represents the number of elements to read from the list and write to the file • The title should be written to the file before writing data from the list.

def test_write_most_frequent():
   print("testing write_most_frequent")
   list1 = [("a",27), ("bc",25), ("defg",21), ("hi",21), ("jk",18),
           ("l",17), ("m",16), ("nop", 15), ("qr", 14), ("s", 13),
           ("t",10), ("uv",9), ("x",5), ("yz",2)]
   write_most_frequent("test_output.txt", list1, 5, "Alphabet Statistics")
   # Should append to a file called test_output.txt the following:
   # Results for Alphabet Statistics:
   # a: 27
   # bc: 25
   # defg: 21
   # hi: 21
   # jk: 18

   write_most_frequent("test_output.txt", list1, 12, "Large Alphabet Statistics")
   # Should append to a file called test_output.txt the following:
   # Results for Large Alphabet Statistics:
   # a: 27
   # bc: 25
   # defg: 21
   # hi: 21
   # jk: 18
   # l: 17
   # m: 16
   # nop: 15
   # qr: 14
   # s: 13
   # t: 10
   # uv: 9

-------------------------------------
# (str, (list of tuple), int, str -> None)
# appends to the file named filename data from the first
# n elements found in the given list; assumes the list is sorted;
# the title given should be written on its own line first
def write_most_frequent(filename, list, n, title):
   print("Fix me")

In C create a program that stores contact info. The program must have the following features:

• Able to store First Name, Phone Number and Birthday (MM/DD/YYYY)
• Able to search for a specific contact using First Name, Phone Number and Birthday (find)
• Able to delete a specific contact using First Name, Phone Number and Birthday (delete)
• Print entire contact list
• Show number of entries in contact list
• Able to save Contact List to file (save)
• Able to load Contact List from file (load)
• Able to exit program (exit/quit)

The program must have the following structure:

• Makefile that completely builds the entire project
• Main file and library (implementation and header files with header guards)
• Neat and Tidy code
• Must have meaningful comments
• Program must have a command and argument structure
• Must use a linked list or dynamic array for contact list (NO REGULAR ARRAYS)
• NO GLOBAL VARIABLES
• Must use dynamically allocated memory that is correctly managed
• Must use pointers
• Must use a decision structure
• Must give user feedback for all input (“contact list saved”, “entry ‘<user input>’ deleted”, etc.)
• Must keep contact list sorted by First Name (sort as a new entry is added)
• Use binary searching algorithm to find entries in contact list
• All program features must be implemented as a function in a library.

Extra credit:

• Used meaningful typedefs
• Used enumerated data types
• Used conditional operator in an inline if
• Ask user to save contact list if they haven’t already before exiting

1. Consider the matrix list x = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]. Write a list comprehension to extract the first column of the matrix [1, 4, 7]. Write another list comprehension to create a vector of twice the square of the middle column.

Q: Let’s say you have an unordered list of numbers and you wanted to put them in order from lowest to highest value. How would you do that? You’re probably thinking that you would just look at all the numbers, find the lowest number and put it at the beginning of your list. Then you would find the next largest number and put it in the second spot in the list, and so on until you’ve ordered the entire list of numbers. It’s simple, basic, and not very exciting. Now, let’s say that instead of ordering the list yourself, you decide it’s a better idea to write a computer program to order the list for you. Now you don’t have to deal with moving the numbers around, you just need to tell your program how to move the numbers, and then let the program handle any list you give it.Identify all possible ways of telling your program how to move the numbers, where each way provides the required result.

(Note: The program code is preferred to be in Java)

There are wide applications of the searching algorithm, where given a list of objects, to find whether the search target is in the list.

The intuitive solution is that we walk through the list until the search target is found or the end of the list is reached. The solution is called Linear Search.

For general purpose, let us use ListADT and define a static generic linear search method as follows:

public static <T extends Comparable<T>> int search(ListADT<T> array, T targetValue) throws EmptyCollectionException;

Please implement the linear search method, which walks through the given list and search for the targetValue until the targetValue is found or the end of the list is reached. If the targetValue is found, the method returns the index of the targetValue in the list or else it returns -1.

public static <T extends Comparable<T>> int search(ListADT<T> array, T targetValue) throws EmptyCollectionException {

}

In the hands-out or your sketchbook, please write down your code and take a snapshot and submit it.

Additionally, discuss and answer the following question:
